Other Parts Discussed in Thread: TPS53355
Can you tell me what the unity gain is on these two parts. Marvell uses a TPS53355 part with a feed back loop to keep the voltage level stable at the switch chip. Their application note says any regulators can be used that have a unity gain bandwidth in the range of 15-300Khz. Do these have that as I'm having issues with the TPS53355 part and i have used these two other one with no issues.
